MIXING-MACHINE.

Specification of Letters Patent.

Patented May 2, 1916..

Application filed February 25, 1914. Serial No. 820,810.

To all' whomy t may concern Be it known that I, Ci-i \1.;1is'i\'li.\1i, a citizen of the United States, and a resident of Holgate, in the county of Henry and State of Ohio, have invented a certain new and useful MixingMachine; and I do hereby declare the following to bea full, clear, and exact description of the invention, suoli as will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, and to the characters of reference marked thereon, which form a part of' this specification.

My invention relates to mixing machines.

It has for its object to provide a means for making proportionate mixtures and regulating the amount of the elements which enter into resultant compositions.

My invention is particularly advantageous when used in mixing elements which combine in the formation of concrete. lWhen used for that purpose, the cement, stone and sand are mixed together iii proportions which differ according to the character for which the concrete is to be used. The proportions may be regulated by adjustable elements contained in the machine.

The invention may be contained in many constructions all of which come within the purview of the claim hereinafter appended. To show the practicability of constructions embodying my invention, I have selected one of such constructions as an example and shall describe it hereinafter. The construction selected is illustrated in the accompanying drawings.

Figure 1 is a side view of a machine em bodying the invention, part of the machine being shown broken away and part in section in order to more clearly illustrate the elements of the machine. Fig. 2 is a view of a detail usable for cleaning, one of the mixing troughs. Fig. 3 is a top view of the machine shown in Fig. 1, a part being removed to show some of the mechanism.

In the figure, 1 is the frame or body of the machine which is supported on the front and rear wheels 2 in order that thel machine may be easily transferred from place to place. driving the parts of the mechanism. 'I he engine El is shown as supported centrally upon the frame 1. A double hopper 4, loy cated on the frame 1,'is 1arovided with aseparating partition 5. The partition 5 An engine 3 may be provided forl may be made removable if desired. The lower end of the hopper et is closed by a slidable bottom 6, supported at its ends lin the channels 7.- The bottom 6 is located in spaced relation with respect to the end walls S of the mouth of the hopper 1. The lower end of the partition 5 extends to 4a point in close proximity to the shiftable bottom 6. As the bottom 6 shifts back and forth in the grooves 7, the material contained on one side of the partition 5 in the hopper l, will fall through the space formed between the edge of the bottom and the lower edge of the end wall 8 located on that side of the hopper. `When the bottom 6 is shifted, the material contained in the opposite side of the partition. will fall from the other chamber of the hopper through the space formed between thel edges of the end wall and the bottom located on that side. This will be on the side opposite the direction in which the bottom is shifted. The

proportionate amounts of material that will pass through the space between the bottom and the end walls of the hopper may be varied by means of .a shutter or damper plate 9 secured to one end wall of the mouth of the hopper by means of bolts 10 located in slots formed in the plate 9. The ratio of the material that will be allowed to pass out from the chambers of the hopper, may thus be varied according to the position of the lower edge of the plate 9 which may be adjusted with respect to the spaceformed between the edge of the end wall of the mouth of the hopper and the edge of the movable bottom. The lower the plate 9 is positioned with respect to the lower edge of the end wall of the mouth of the hopper, the less will be the amount of material that is allowed to pass out of the chamber located on that side of the'partition.

A suitable means' is provided for shifting the bottom 6 back and forth to permit`4 the material to fall first from one chamber of the hopper and then from the other. I have provided a link or whip-rod 12 which is connected to the bottom by meansof the bifureated bracket or ears 13 at one end, and to the crank shaft 11 at the other end. The crank and its shaft 14 is rotated by means of the sprocket wheel 15 and chain 16 .which is connected to the engine 3 through suitable driving mechanism. As the crank shaft 14 is rotated, the bottom 6 is slid back and forth in the channel 7. The link 12 may ilo be made rectangular in form as shown in Fig. 1, in order to permit the material to freely fall from the hopper 4 and prevent the material from striking the link asfit falls from the hopper. f

As material falls from Iirst one edge of the bottom and then from the other edge, 'it descendsto an apron 20 and to the trough 21.' The apron 20 andthe trough 21 may be made of sheet metal ,suitably supported by the frame 1. The apron 20 guides the material that falls thereon to the'trough 21. In the trough 21, the materials which fall from the co-mpartments of the hopper 4, are

mixed by means of a mixing device such as the beater 25. It consists of a drum 26 having radially extending arms 27 which extend into and to near the bottom of the trough 21. The arms 27 are secured to the drum 26 by bolts 28. The drum is rotated by the sarocket wheel 29 and chain 30. lhe arms 2 are located in spaced relation around the drum and along the drum, as shown in Figs. 1 and 3. Theyfoperate to mix the materials in the trough 21 and at .Y -the same time work them from one edge of the trough 21 through and up over the other edge of the trough 21 as the drum 26 is'ro tated. The materiall then falls upon the apron 35, and is directed thereby to the trough 36 toward which the apron 35 is inlclined. lThe trough 36 is madel of'sheet iron and is suitably strengthened and supported by parts of the frame 1. A conveyer 37 is locatedin the trough 36 and operated by the pulleywheel 39 and belt 40; The belt is driven by suitable driving mechanism. The conveyer 37 maybe the'ordinary screw conveyer or it may be provided with plows 41 having faces so inclined. with respect to the axis of'the supporting shaft 42 as to work the material to the mouth 43 ofthe trough 36. rfhe mouth 43 is located on one side of the frame 1 and in position so that receptacles, such as pails or Wheel barrows, may be placed beneath-the mouth and the materials collected. The plows not only op` erate to .conveythe material to the mouth of the trough, but also operate to further mix the materials directed into the trough.

'In the operation of the device, the materials may be mixed dry in the trough 21' which will require but comparatively little power and then directed into the trough 36 to which a fluid may also be directed and the materials may be 'mixed'wet therein. This l,is of particular advantage in'making concrete mixtures. Water may be directed through the pipe 45 Aand Ivalve 46 into the tro-ugh 36v and the mixture directed into the trough 36 may be 'saturated to the degree required according to the pur-poses for which the resultant mixture is to ybe used.

The mechanism for driving `the parts of the'mixlng machine, recelves its power from the engine 3 which drivesthe pulley 50 and the iy-wheel 52 by means of the belt 51.

The pulley 50 and the iiy-wheel 52 are suit-L 29 to which it is connected, by the sprocket chain 30. This causes the plows 41 secured to the shaft 42 to rotate and convey the material through the trough 36 to the mouth 43 and also mixes the mixture lifted from the trough 21 into the trough 36 with the water which is directed through the pipe 45. This also rotates the `drum 26' which mixes the dry mixture coming from the hopper 24 and works the material 'from one side of the trough 29 to the other side of "the trough and lifts it onto the apron 35 from whence it falls to the trough 36. The gear 59 is keyed to. the shaft of the drum and, drives the sprocket wheel 15 through the chain 16. The sprocket wheel 15 being keyed to the crank shaft 14, it causes the bottom 6 to slide back and forth permitting the material to fall first from one chamber of the hopper 4 and then from the other chamber in regular amounts and in amounts which may be varied in proportion according to the position of the plate 9 relative to the lower edge of the end wall of .the mouth of the hopper on which it is located.

If desired, the trough 21 may be entirely cleared of its contents by means of the angular plateGO shown in Fig. 2. One of the sides of the plate 60 is provided with openings 61. The angular plate 60 may'be placed on the drum, the radial arms 2'? extending' through the holes 61. The drum 26 may then be rotated .whereupon the rods 27 located behind one of the sides of the plates 60 will push the plate 60 before it and clear the trough 21 from the material contained therein. The trough 21 may thus be scraped Aclean by the'plate 60.

The construction selected and described may be greatly varied in the arrangement and construction of its parts and vin the substitution of the elements havlng equivalent functions and such modifications may still contain the invention which is described in trough, an apron for feeding the material to one side of the drum and one edge of the trough, means for rotating the drum for mixing the material dry and conveying it only transverse across the trough at right angles to the axis of the drum and over the edge of the trough opposite to'that over which the materials are fed, a second trough extending parallel with the first-named trough for receiving the-material therefrom,

l and a pipe for directing Water 'into the H. H. HUs'roN, G. H. LAMPMAN.
